The RC4 Curv is new in the Fischer product line. These are not Full Fit Vacuum; they are called “Powered by Vacuum”. The lower only is vacuum fit. A byproduct of the experimentation with Vacuum Fit technology (also with other manufacturers offering shell customization) is the recognition that ski boots must fit out of the box and shaping should be offered as an option. Though compelling, the Full Fit Vacuum lost some momentum, some due to an uneven and “generic” out-of-the-box fit. Last shape is important.

Fischer, from Austria where snow sports in general and skiing in particular is in every strand of Austrian DNA, has been diligent about correcting existing flaws in their product. The 97mm Fischer Curv has a better internal shape and vastly improved liners, initial fit is much more anatomical.

The Curv features two sheets of thermo-moldable composite (Aramid) on both medial and lateral aspects of the shell-clearly visible-that reduce shell deflection when flexing forward and enhance torsional stiffness. It works; turn initiation is ultra positive and altering trajectory needs only a subtle big-toe/little-toe touch.

Fischer remains committed to the Soma stance-abducted or “duck footed”-that they have advocated since entering the boot market. This still provides a very intuitive feel about the boots…easy and early into the turn and great power off. For contemporary skis this is a real benefit, encouraging proper technique and rewarding the skier for it.​As we’ve stated in just about every review of Fischer ski boots posted on our site, Fischer’s Soma stance complements woman’s physiology. The potential for torsional stress induced by medial deviation of the knees created by Q-angle is lessened by the abducted stance because it does initiate turns early. This may be construed as a generalization but there is plenty of anecdotal evidence.

The RC4 Curv 120 and ladies My Curv 90 are medium volume; heel and mid-foot are close fitting out-of-the-box. Instep height has good room, forefoot width is @97mm is shaped well and the toe box radius and height allow good wiggle room. Naturally with Vacuum, the fit can be refined.
